INTERIOR-HEATING SYSTEM.

Specication of Letters Patent.

Application filed February 16, 1911.

To all whom 'it may concern:

Be it known that I, EDGAR M. MATTHEWS, a citizenof the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Interior-Heating System, of which thefollowing is a specification.

My invention is intended for use, more particularly, in railway-carswhich are provided with hollow metal sash for the windows; my objectbeing to enable the windowsash to be utilized as a medium through whichto heat the car.

The invention is adapted, however, for interior heating systemsgenerally, where the sash employed for the windows of the inelosure isof metal and hollow.

In the accompanying drawings, Figure 1 is a broken sectional view of apassengercar, showing the interior thereof in side elevation, with twowindows equipped with my improvement, the sash of one window beingclosed and that of the other raised; Fig. 2 is an enlarged section online 2, Fig. 1, and Fig. 3 is an enlarged section on line 3, Fig. 2.

While my invention is designed to be employedin connection with anyconstructlon of hollow metal window-sash, I have selected forillustrating it the sash shown andl described in Letters Patent No. 977,415, granted to me November 29, 1910, which need not, therefore, bedescribed in detail herein, but the general construction of which may bedescribed as follows:

A suitable sheet-metal blank, for a hollow sash 4 ot rectangular shape,is bent to form top, bottomv and side rails, with a seat-forming recess5 about the inner edge of the sash for seating trough-shaped rubbercushions 6 in which the window-pane 7 is confined about its edges, beingclamped in place by hollow metal beads 8 fastened in position to bearagainst the inner sides of the cushion. The beads, which are also formedfrom a sheet-metal blank of proper shape, are provided with tongues 9 tofit in inclined sockets 10 formed in the rails.

The car 11 is equipped with any suitable heating system of ordinarytype, that shown comprising steam-pipes 12 runmng along the sides nearthe 'floor of the car and connected under the car-seats 13 withsteamcoils 14. In the sash 3 of each window, or of as many windows asmay be desired, is

a chamber 15, formed by a flanged plate 16 evtendinflr lengthwisethrough each rail, the chamber eing packed about its walls with asuitable heat-insulating lining 17, preferably asbestos, to prevent thesurfaces of the rails inside the car from becpming excessively hot wherepassengers might touch them.y Perforations 18 are provided through theinner faces of the chamber for the circulation of air through it. Asteam-pipe 19 is housed in the chamber 15, and is fed from a steam-pipe12, to constitute it a heat-conductor by circulating steam through it,by a branch-pipe 20 rising from .the pipe 12 through the window-stool 21into the pipe 19. The pipe 20, which is shown to be equipped with avalve 22 for permanently opening or closing the supply of steam to thesash, also contains a rotary valve 23 for temporarily opening and elosinthe same by lowering and raising the sas To that end the valve 23 hasits stem 24 provided with a handle 25 carrying a link 26 on its outerend, which is pivotally connected with the lower end of avertically-reciprocable push-rod 27 extending from it through the stool21, with a spring 29 confined about it for raising it to close thevalve23, the rod terminating at its upper end in a head 30 fitting a recess31 in the stool when the head is depressed, to countersink it. The headis in the path of the lower sash-rail, whereby when the sash is down toclose the window the rod 27 is depressed to open the yalve 23 (the valve22 being normally open when my improved system is in use and normallyclosed when it is out of use), permitting steam to circulate through thepipe 19 to heatl the air circulating through the cham ber 15. Adjacentto the chamber is provided, to extend about its inner face, as usual, astop 32, which in the present case is formed hollow of sheet-metal andprovided with perforations 33 through its wall adjacent to the chamber,to register with the perforations 18, and with similar perforations 33in its opposite wall and top to discharge into the car the air whichenters it from the chamber 1'5 and is heated therein by its containedsteam-pipe 19.

What I claim as new and desire to secure by Letters Patent is- 1. Incombination with an inclosure, a hollow window-sash forming an airpassage closed on its outer side and provided with perforations onitsinnerI side, and means for supplying heat to said air-passage, for thepurpose set forth.

2. In combination with an inclosure, a hollow window-sash forming anair-passage closed on its outer side and provided with perforations onits inner side, a heatconductor in said air-passage, and means forsupplying heat to .said conductor, for

the purpose set forth.

3. In combination with an inclosure, a hollow window-sash forming anVair-passage closed on its outer side and provided with perforations onits inner side, a heat conductor in said air-passage, means forsupplying heat to said conductor, a valveequipped connection betweensaid means and vconductor for supplying heat t0 the latter,

and a spring-pressed rod connected with the stem of said valve andextending into the path of movement of the sash, for the purpose setforth'.

4. In combination with an inclosure, a

hollow window-sash formin an air-passage therein closed on its outer sie` and provided with perforations on its inner side, a heat conductor insaid air-passage, means for supplying heat to said conductor, and ahollow stop for the sash at the inner side thereof havingv perforationscommunicating with the air-passage in the sash and the inclosure,whereby the heated air is caused to circulate through said air-passageand stop and into the inclosure, as set forth.

5. In combination with an inclosure," a

hollow window-sash forming an air-passage steam-pipes for supplyingsteam-heat to the car, steam-pipes in said air-passages and branch-pipesleading from said steam-supplying pipes into the pipes in saidair-passaves, for the purpose set forth.

In combination" with a railway car, hollow Window sashI formingairpassages therein closed on their outer sides and rovided withperforations on their inner sides, steam-pipes for supplying steam-heatto the car, steam-pipes in said air-passages, branchpipes leading fromsaid steam-supplying pipes into the pipes in said air-passages, a s

valve on each branch-pipe and a sprlngraised push-rod connected with thestem of the valve and extending into the path of movement of thecorresponding sash, for the purpose set forth.

8. In combination with a railway car, hollow window-sash formingair-passages therein closed on their outer sides and provided withperforations on their inner sidesz steam-pipes supplying steam-heat tothe ear, steam-pipes in said air-passages, branchpipes leading from saidsteam-supplying pipes into the pipes in said air-passages, and hollowperforated stops for the sash at the inner sides thereof andcommunicating with said air-passages and the interior of the car,

for the purpose set forth.

9. In combination with a railway ear, hol-` low window sash forming airpassages therein closed at their outer sides and pro- Videdwithperforations' on their inner sides, steam-pipes for supplying steam-heatto the car, steam-pipes in said air-passages, branchpipes leading fromsaid steam-supplying lpipes into the pipes in said air-passages,"

valves in the branch pipes, meansfor opening and closing said Valves byclosing and opening-the Window-sash, and hollow perforated stops for thesash at the inner sides thereof and communicating with said airpassagesand the interior of the car, for the purpose set forth.
